Lotide

A mini clone of the Lodash library.

Purpose

BEWARE: This library was published for learning purposes. It is not intended for use in production-grade software.

This project was created and published by me as part of my learnings at Lighthouse Labs.

Usage

Install it:

npm install @ojripley/lotide

Require it:

const _ = require('@ojripley/lotide');

Call it:

const results = _.tail([1, 2, 3]) // => [2, 3]

Documentation

The following functions are currently implemented:

• head(array) -> returns the first element in an array
• tail(array) -> returns the last item of an array
• middle(array) -> returns the middle item of an array, or an empty array if the length is less than 3
• assertEqual(actual, expected) -> asserts the equality of two primitive type values
• assertArraysEqual(array1, array2) -> asserts the equality of two arrays
• assertObjectsEqual(object1, object2) -> assertation for comparing two objects
• countLetters(string) -> returns on object with an array for each letter found in the string and its count
• countOnly(allItems, itemsToCount) -> returns an object of the items specifed to count by itemsToCount from allItems
• eqArrays(object1, object2) -> determines object equality
• eqObjects(obj1, obj2) -> returns true if two objects are equal
• findKey(object, callback) -> finds the first key occurance that matches the condition determined by the callback function
• findKeyByValue(obj, value) -> returns the value of the key specified in an object
• flatten(array) -> flattens in arrays into the same level as the outter array. The flattened array gets returned and the originla remains unmodified
• letterPositions(string) -> returns an object of letters with an array assigned to each containing the index positions of each occurance of the letter
• map(array, callback) -> returns a new array with the changes implemented on the original as decided by the callback function
• takeUntil(array, callback) -> returns a new array with values taken from the original until the condition determined by the callback function is met
• without(sourceArray, itemsToRemoveArray) -> returns a new array with any matching items between the source array and the remove array removed
